class shark::LineSearch&lt; SearchPointType &gt;</div><p>Wrapper for the linesearch class of functions in the linear algebra library. </p>
<p>This class is a wrapper for the linesearch class of functions of the linear algebra library. The class is used for example in <a class="el" href="classshark_1_1_c_g.html" title="Conjugate-gradient method for unconstrained optimization.">CG</a> or <a class="el" href="classshark_1_1_b_f_g_s.html" title="Broyden, Fletcher, Goldfarb, Shannon algorithm for unconstraint optimization.">BFGS</a> for their internal linesearch learning steps. It is NOT an Optimizer on its own, since it needs the Newton direction to be specified. </p>
